LMK03318: Single-ended AC coupled clock input

Graeme Parker

Part Number: LMK03318

Hi,

We are replacing an Si5324 (unobtainable) with your LMK03318. We currently have a single-ended AC coupled clock input and wish to do the same with the LMK part. What would be the correct connectivity in this case?

Hi Graeme,

LMK03318 has AC coupling caps at the PRIREF pins. For SE inputs, connect unused input directly to GND.

I see there is a XTAL as well, for LMK03318 XTALs must be connected to SECREF pins.

Regards,

Vicente
